Abstract

The invention provides a flexible supporting and clamping method and device for the inner wall of a honeycomb material. The device comprises a vibration table, a conversion plate, a liquid storage cavity and a grating plate, the bottom of the liquid storage cavity is connected with the vibration table through the conversion plate, the liquid storage cavity is used for containing a non-Newtonian fluid injected in the machining process, and the grating plate is matched with the honeycomb material and the liquid storage cavity and is arranged at the bottom of the liquid storage cavity. On one hand, the grating plate is used for supporting and positioning the honeycomb material, on the other hand, the grating plate is matched with the honeycomb material to form a relative movement trend, vibration energy is transmitted to the non-Newtonian fluid in the liquid storage cavity, and the honeycomb material is fixed after the non-Newtonian fluid is subjected to shear phase change. The vibration table is used for increasing horizontal vibration of the honeycomb material, on one hand, non-Newtonian fluid phase change fixing of the honeycomb material is achieved through the shear thickening characteristic of the non-Newtonian fluid, and on the other hand, intermittent contact of the honeycomb material and a cutter in the horizontal direction is achieved; and lattice deformation and crushing damage caused by buckling of the honeycomb material are reduced.

Description

technical field

[0001] The invention relates to the technical field of honeycomb material clamps, in particular to a method and device for flexible support and clamping of the inner wall of a honeycomb material. Background technique

[0002] Honeycomb material is a composite material with light weight, high strength, impact resistance, fatigue resistance, good insulation performance and sound insulation. However, the honeycomb material is a typical difficult-to-process material. The superposition of the honeycomb porous structure and the anisotropy of the honeycomb wall brings great challenges to the processing of the honeycomb material. During processing, the honeycomb wall is in a state of buckling deformation from the moment it comes into contact with the tool until it breaks, and it continues to intensify as time goes by, resulting in cell deformation and crushing of the honeycomb material. In addition, the honeycomb structure has problems such as easy deformation, diff...
